The previous limitations of using eddy current sensors have now been redefined with Embedded Coil Technology (ECT). This method makes use of the latest materials and manufacturing technologies and so clearly differentiates itself from conventionally wound coils. In doing so, the sensor design is embedded with stability in terms of both thermal properties and shape/form by using an inorganic carrier material. Even electronic components can be placed on this carrier material.
Eddy current sensors that use ECT are able to resist extremely high mechanical loads over longer periods, as is proven by the sensor’s use on refiners in the paper industry, where it is used to measure the grinding gap. The sensors offer extremely high temperature stability in the alignment of mirror segments on giant telescopes, where they also provide micrometre precision across a clear, starry sky. eddyNCDT ECT sensors are hermetically sealed for semiconductor manufacture. This means the sensors can be used in ultra high vacuums. Due to its high thermal stability, ECT sensors are suitable for use in temperatures up to 350°C. The sensor can also be adapted to almost any installation requirements and if necessary can also be designed to incorporate the complete electronics within the sensor itself.
